I can't even launch a satellite with a single dish. I made a Kethane scanner/ISA Mapper satellite. If I try and launch it the game either crashes, or the launch scene never loads. Removing the MAPSAT dish fixes the issue. I'm not seeing any unusual RAM usage. I have yet to test with no other mods installed, but that's irrelevant because I'm never going to be using just MAPSAT. I'm going to run a few more tests, but right now it seems like the problem is MAPSAT-specific. To be expected with a dev version .
